[Dwarf-Discuss] DW_AT values unknown to me.

Green Hills has never contacted us about DWARF implementation or 
submitted any proposals to the DWARF Committee.

Many years ago, I was on an ABI committee with Greg Davis, who I believe 
is Director of Engineering at GHS.  You might contact him for 
information about these attributes.  The last email I have for him is 
gdavis at ghs.com.
